The time to separate the effluent phases of the LLFR at the highest experimental values of conversion and yield, reactor of L/Lmax 1.0, palm oil flow rate 9.0 g min-1 and 1.0% of NaOH as catalyst, was less than 5 min, while usually the residence time in separators down stream of the tubular reactor ranges between 15 min and 2 h [3]. The presence of emulsions or gels was not observed
